Also have a look on technet for the underlying o/s error (183) that might help.

Good CEST morning.
I try to run two instances out of one oracle_home on a Windows 2008R2 server (bad OS, but not my choice).
Problems are, that all databases are using the DIAG directory (crates a new subdir with the correct SID anyway) configured by the instance that has been configured last. And the second instance fails with ugly semaphore errors. I think they try to use the same ressource for the same reason they use the same DIAG dir.

My questions are: I have no ORACLE_SID configured on system level. How does the box determine the oracle_sid used for a process in services.msc?
Second: After establishing the instances with DBCA, everything was well, the insatnces did run simultanously. After stopping/starting both services, the mess described above happened. Do I have a wrong setup somehow?
I want to use one oracle_home, because I want to avoid different patch levels and messing around with setting/changing ORACLE_HOME all the time.
Thanks in advance!
